Understanding the Turkish ISUP Feature

The Cisco BTS 10200 Softswitch provides support for the Turkish ISUP variant. The Turkish ISUP feature is based on the ITU-T Q.767 specification and the Turkish-ISUP implementation in the PGW 2200 softswitch. This feature delivers the Cisco BTS 10200 Softswitch to the Turkish markets requiring SS7 network interconnect through the Turkish ISUP protocol variant.

The features and services supported in Turkish ISUP are organized into the following categories:

Note In the Cisco BTS 10200 Softswitch, the default values in the configuration tables for Trunk Group (TG) profile are not specific to any variant. It is expected that you will provision the TG profile with variant-specific timer values. For example, if a Turkish ISUP customer requires that BTS follow the Turkish ISUP-specific timer values at the ISUP level, the values should be configured in the SS7 Q767 Trunk-Group profile. This profile should then be used when the Turkish ISUP Trunk-Group is provisioned.

Operating

A new value has been added to the installed default variant base to support Turkish ISUP. It introduces the value Q767_TURKISH for the ID token in the User Part Variant Base and User Part Variant tables.

To use the Turkish-ISUP feature, you need to perform the following configurations in the EMS CLI:

•Add Q767_TURKISH as the user-part variant id in the User Part Variant table.

•Specify Q767_TURKISH as user-part-variant-id while you are configuring the call control route of a Q767 Turkish trunk in the Call Control Route table.
